Answer:
He cant rent the car for 5 days
Step-by-step explanation:
21 * 5 = 105
0.10 * 250 = 25
105 + 25 = 130
He only has 115 to spend
Let x = Edna's age
then it follows that (x + 1) is Ellie's age and (x + 2) is Elsa's age
We can now write and equation for the sum of their ages equal to 108:
x + (x + 1) + (x +2) = 108 simplify the left side
3x + 3 = 108 subtract 3 from both sides
3x = 105 divide both sides by 3
x = 35
Edna is 35, Ellie is 36, and Elsa is 37
Answer:
x = 11
Step-by-step explanation:
7x + 3(3x + 6) = 194
<em>open the parenthesis</em>
7x + 3 * 3x + 3 * 6 = 194
7x + 9x + 18 = 194
<em>subtract 18 from both sides of the equation</em>
7x + 9x + 18 - 18 = 194 - 18
<em>combine like terms</em>
7x + 9x = 194 - 18
16x = 176
<em>divide both sides of the equation by 16</em>
16x/16 = 176/16
x = 176/16
x = 11
